Infini IV ?
What is the Infinity IV model? Is it just a japanese spec rx-7, or is it some kind of performance model? Also, if it is a better performer than a Turbo ll would it be feasable to buy one? Thanks

From my website:
Also in 1991 Mazda created the Japanese market only Infini IV (pronounced on'-fin-ee) .
Stripped of all Savanna or RX-7 identification, this was the last limited edition ultra high performance version of the 2nd-generation RX-7. A factory hot rod, the Infini IV was lightened (to 2770 lb.), by stripping out the extras, reducing the noise dampening material and using lighter parts including lightweight, perforated suede like material racing style seats. With a revised suspension (shocks 25% stiffer, springs 10% stiffer and lowered 1") Special Pirelli designed P-Zero tires, ultra lightweight 16 inch BBS wheels and a bright red front strut brace, the handling improved to a skidpad of .91 Gs. The Infini IV (as with most 91 models) also came with the tighter steering rack from the 89-90 North American GTUs model. Molded knee Pads at the driver's door side and center console were added to help brace the driver's legs while cornering, while a "dead pedal" bar ran the length of the passengers floor. An emergency flare and holder were also mounted just under the glove box.
Similar again to the US spec 1989 and 1990 GTUs; the Infini IV came with the 4.3 rear end final gear (but also used a new Torsen Limited Slip Differential), minimal extras, but no air conditioning, or even a CD/Cassette (however it did come with power windows and used the light weight power window motors from the convertibles). Power was bumped to 215 HP (JIS), largely by changing the exhaust to a free flowing design and revised ECU. 0-60 performance was 6.5 and the quarter mile time dropped to 14.9, with Infini specific brake pads helping make an impressively matching braking force of 60-0 in 141 ft (8 feet less than the standard RX-7 Turbo). The Infini IV was only available in a custom black/green metallic paint (Nobel Green Pearl Clearcoat, Mazda paint code VQ). Unfortunately, the Infini IV was not imported to North America other than a single press version that was returned back to Japan after the press tour.

And none of the other FC Infini's were any lighter or more powerful than the standard Turbo of that year.

show me one...
Its been long published (in multiple locations and print)that the Infini IV was 2770 lbs.
Since the S5 Turbo was 2980... well you do the math.
So again, don't post information that you don't know for sure

no i didnt, he just had one in stock and told me he had one, no extra charge, and i know it wouldnt matter anyways, because i got a much better port and rebuild and a couple of other little things. all the manifolds flow better, and the turbo ive heard from many ppl is a little bit better too, not really enough to make a huge difference
